We currently plan to disallow use of filp_open() from drivers in GKI,
however the ZRAM driver still needs it. Add a new GKI-only variant of
filp_open() which only permits a block device to be opened, which can
be exported instead. This keeps ZRAM working but cuts down on drivers
that attempt to open and write files in kernel mode.
